Little Big Town: Kiddie Critic

Phillip Sweet says while rehearsing the song at home, he got some tough criticism from his nine-year-old daughter,Penelope.

"We'd been rehearsing some Bee Gees stuff so I was humming the Bee Gees song around the house. My daughter was like, 'Hey dad who sings that song?' I said, 'Oh, it's The Bee Gees.' She's like, "Let's keep it that way.' - Phillip.
